β-Cyclodextrin (β-CD) (CAS: 7585-39-9), Cyclodextrins xa mus rau tsev neeg ntawm cov khoom sib txuas uas muaj cov piam thaj molecules khi ua ke hauv lub nplhaib (cyclic oligosaccharides).Nws yog tsim los ntawm starch los ntawm enzymatic hloov dua siab tshiab.Beta-cyclodextrin yog 7-tus tswvcuab qab zib nplhaib molecular daim ntawv ntawm cyclodextrin.Cyclodextrin muaj ntau yam kev siv.Hauv kev lag luam kws tshuaj, nws tuaj yeem siv los ua cov neeg ua haujlwm nyuaj rau kev ua kom cov tshuaj soluble tsis zoo nrog rau kev ua kom lawv cov bioavailability thiab stability.Nws kuj tseem tuaj yeem txo cov tshuaj lom hauv plab hnyuv, thiab tiv thaiv kev sib cuam tshuam ntawm cov tshuaj-tshuaj thiab tshuaj-excipient.Nws tseem tuaj yeem siv rau hauv cov zaub mov, tshuaj, xa tshuaj, thiab tshuaj lom neeg kev lag luam, nrog rau kev ua liaj ua teb thiab ib puag ncig engineering.
β-Cyclodextrin yog siv los ua ib tug complexing neeg sawv cev nyob rau hauv kev xa tshuaj vim hais tias nws tsim ib tug inclusion complex nrog ib tug tshuaj molecule.Lub complex ntawm cyclodextrin tsub kom lub aqueous solubility, dissolution tus nqi thiab bioavailability ntawm cov dej-soluble tshuaj tsis zoo, uas yog ib qho tseem ceeb rau kev xa tus neeg saib xyuas kev kho mob mus rau ib tug lom system.
Cyclodextrins tshwm sim li dawb, xyaum tsis muaj ntxhiab, zoo crystalline hmoov, muaj ib tug me ntsis qab zib saj.Qee cov cyclodextrin derivatives tshwm sim raws li amorphous hmoov.Beta-Cyclodextrin yog ntau tshaj thiab pheej yig cyclic oligosaccharide uas tsim cov kev sib koom ua ke nrog ntau cov tshuaj molecules.Nws daim ntawv thov tseem ceeb yog nyob rau hauv ntsiav tshuaj thiab tshuaj ntsiav formulations.
Cyclodextrins yog 'bucketlike' lossis 'conelike' toroid molecules, nrog cov qauv nruj thiab lub hauv paus kab noj hniav, qhov loj ntawm qhov sib txawv raws li hom cyclodextrin.Sab hauv ntawm kab noj hniav yog hydrophobic thiab sab nraud ntawm lub torus yog hydrophilic;Qhov no yog vim qhov kev npaj ntawm hydroxyl pawg hauv cov molecule.Qhov kev npaj no tso cai rau lub cyclodextrin kom haum rau cov qhua molecule nyob rau hauv kab noj hniav, tsim ib tug inclusion complex.
Cyclodextrins tuaj yeem siv los tsim cov kev sib koom ua ke nrog ntau yam tshuaj molecules, uas ua rau feem ntau txhim kho rau kev sib cais thiab bioavailability vim kev txhim kho solubility thiab txhim kho tshuaj lom neeg thiab lub cev ruaj khov.
Cyclodextrin inclusion complexes kuj tau siv los npog qhov tsis hnov tsw ntawm cov ntaub ntawv nquag thiab hloov cov kua ua kua rau hauv cov khoom siv.
β-Cyclodextrin yog cov feem ntau siv cyclodextrin, tab sis nws yog qhov tsawg tshaj plaws soluble.Nws yog qhov kim tshaj plaws cyclodextrin;yog muag los ntawm ntau qhov chaw;thiab muaj peev xwm tsim inclusion complexes nrog ib tug xov tooj ntawm molecules ntawm kws tshuaj paj.Txawm li cas los xij, β-Cyclodextrin yog nephrotoxic thiab yuav tsum tsis txhob siv rau hauv cov tshuaj parenteral.β-Cyclodextrin feem ntau yog siv hauv cov ntsiav tshuaj thiab tshuaj ntsiav tshuaj.
Hauv cov ntsiav tshuaj ntawm qhov ncauj formulations, β-Cyclodextrin yuav siv tau nyob rau hauv ob qho tib si ntub-granulation thiab ncaj-compression txheej txheem.Lub cev muaj zog ntawm β-Cyclodextrin sib txawv nyob ntawm cov chaw tsim khoom.Txawm li cas los xij, β-Cyclodextrin nyiam muaj cov khoom tsis zoo thiab cov khoom siv roj ntsha, xws li 0.1% w / w magnesium stearate, thaum nws ncaj qha compressed.
Hauv parenteral formulations, cyclodextrins tau siv los tsim cov tshuaj ruaj khov thiab soluble ntawm cov tshuaj uas yuav txwv tsis pub tau tsim los siv cov kuab tshuaj tsis muaj dej.
Hauv qhov muag poob formulations, cyclodextrins tsim cov dej-soluble complexes nrog lipophilic tshuaj xws li corticosteroids.Lawv tau pom tias yuav ua rau kom cov dej solubility ntawm cov tshuaj;txhim khu kev nqus tshuaj rau hauv lub qhov muag;txhim kho aqueous stability;thiab kom txo tau qhov mob hauv zos.
Cyclodextrins kuj tau siv rau hauv kev tsim cov tshuaj, suppositories, thiab tshuaj pleev ib ce.
Cyclodextrins yog hmoov txhuv nplej siab derivatives thiab yog siv nyob rau hauv qhov ncauj thiab parenteral tshuaj formulations.Lawv kuj tau siv rau hauv cov tshuaj pleev ib ce thiab ophthalmic formulations.
Cyclodextrins kuj tseem siv rau hauv cov tshuaj pleev ib ce thiab khoom noj khoom haus, thiab feem ntau suav hais tias yog cov khoom tsis muaj tshuaj lom thiab tsis muaj tshuaj lom.Txawm li cas los xij, thaum noj parenterally, β-Cyclodextrin tsis metabolized tab sis accumulates nyob rau hauv lub raum raws li insoluble cholesterol complexes, ua rau mob nephrotoxicity.
Cyclodextrin tswj qhov ncauj yog metabolized los ntawm microflora hauv txoj hnyuv, tsim cov metabolites maltodextrin, maltose, thiab qabzib;Cov no yog lawv tus kheej ntxiv metabolized ua ntej thaum kawg raug tshem tawm raws li carbon dioxide thiab dej.Txawm hais tias ib txoj kev tshawb fawb luam tawm xyoo 1957 tau qhia tias kev siv cov tshuaj cyclodextrins hauv qhov ncauj yog cov tshuaj lom heev, cov kev tshawb fawb txog tsiaj toxicity nyob rau hauv nas thiab dev tsis ntev los no tau qhia tias qhov no tsis yog li ntawd, thiab tam sim no cyclodextrins tau pom zoo siv rau hauv cov khoom noj khoom haus thiab cov tshuaj noj hauv qhov ncauj ntau. ntawm lub teb chaws.
Cyclodextrins tsis ua rau tawv nqaij thiab qhov muag, lossis thaum nqus tau.Kuj tsis muaj pov thawj los qhia tias cyclodextrins yog mutagenic lossis teratogenic.
